Securely transfer your old emails to a new mailbox
Transfer, back up, or archive your emails locally on your computer — without any web tool, without your passwords leaving your device, and without modifying your source mailbox.
For everyone who does not want to lose their old mailbox
Switching from GMX, WEB.DE, T-Online, Yahoo, or another IMAP account to Gmail, Outlook.com, or a new mailbox?
Then you know the problem: official migration paths are often incomplete, too technical, or designed for business accounts.
mailriva helps you take your emails with you securely, back them up locally beforehand, or archive them long-term — without any web tool and without modifying your source mailbox.
Three simple ways to keep your emails
Transfer emails to a new account

Because personal email migrations often fall through the cracks of official solutions.
mailriva focuses on one clear job: copying emails locally and in a controlled manner — without entering your passwords in a browser and without modifying the source.
Gmail
The classic web-based POP fetch is being restricted or removed. No full-featured, local, folder-aware migration assistant for personal users.
Outlook.com
Microsoft has removed direct support for connecting new third-party accounts. No built-in migration assistant anymore.
GMX / WEB.DE
POP3/IMAP must first be manually enabled — exactly the kind of hurdle where many personal users get stuck.
iCloud Mail
No POP support, and an app-specific password is required. Relevant but not friction-free.
Local app, not an online tool
Your passwords do not need to be entered into a website.
All processing happens locally on your computer. This reduces unnecessary data sharing and supports a privacy-friendly architecture.
Works with your email provider
mailriva supports all major email providers in Germany, Austria, and Switzerland.

Frequently asked questions
Do my passwords leave my computer?
No. The app is designed as a local desktop application. Your credentials do not need to be entered into a website and are not meant to leave your device.
Will my old mailbox be modified?
No. The product is designed so that the source mailbox remains unchanged. Emails are copied, not deleted or moved in the source account.
Can I switch from GMX, WEB.DE, or T-Online to Gmail?
Yes. Exactly these kinds of migrations are a core use case.
Is this an online tool?
No. The app runs locally on your computer.
Can I back up my emails before switching?
Yes. That is what the backup feature is for.
Are contacts and calendars transferred?
No. The focus is deliberately on emails only.
